Event Notification Report for October 03, 2022

AGREEMENT STATE REPORT - GAUGE SHUTTER FAILURE

"On September 14, 2022, a generally licensed fixed gauge (Heuft Model 45US, SN: 2RG017177) containing 40 mCi of Am-241 (Source Model AMC.25, SN: 4479CW) failed to operate/function as designed. The on-off mechanism (e.g. shutter) of the device failed to return to the closed position. The licensee contacted the manufacturer and the device was removed from service. On September 16, 2022, the manufacturer arrived at the facility and repaired the device. Surveys and safety checks were performed by the manufacturer, and it was determined that the likelihood of anyone being exposed to excessive radiation levels is highly unlikely."

Colorado - Event Report ID No.: CO220031

LOSS OF RADIOACTIVE MATERIAL IN TRANSIT

The following information was provided by the licensee via phone:

A shipment of Lutetium-177 was reported lost on September 21, 2022, en route from the University of Missouri to the University of California, San Francisco. The sample was 105 mCi when shipped on September 8 and would be no more than 20 mCi when reported lost on September 21, 2022. The last known location of the package was at the common carrier's facility in Memphis, Tennessee.

THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

AGREEMENT STATE REPORT - LOST SHIPMENT OF H-3 SOURCES (WATCHES)

The following information was provided by the Maine Radiation Control Program via email:

"Maine Radiation Control Program was notified by the licensee (Digilistics) at 1321 [EDT] on Monday, September 26, 2022, [that] a shipment of nine boxes of watches was sent via [a common carrier] from Keytime Enterprises LTD of Hong Kong, China to Time Concepts of Boise, ID. One of the nine packages was not delivered by [the common carrier] to the consignee. The licensee was notified on September 5, 2022, and the Radiation Safety Officer (RSO) contacted [the common carrier] several times in an attempt to track down the missing package. The RSO received a voicemail from [the common carrier] on or about September 13, 2022, stating that [the common carrier] was officially unable to locate the package. The package contained a total of 84 H-3 watches with an activity of 25 mCi each for a total of 2,100 mCi or 2.1 Curies. Time Concepts has filed a claim with [the common carrier] for the lost watches."

AGREEMENT STATE REPORT - STOLEN GAUGE

The following information was provided by the Illinois Emergency Management Agency (The Agency) via email:

"[The radiation safety officer of] NASHnal Soil Testing (RML IL-02440-01) contacted the Agency at approximately 1200 [CDT] on 9/26/22, to report the theft of a Troxler model 3440 moisture density gauge (S/N 29187) from a jobsite in Michigan City, IN, sometime between the afternoon of 9/24/22 and 0700 on 9/26/22. The Illinois licensee was working in the state of Indiana under Nuclear Regulatory Commission jurisdiction under reciprocity. Local law enforcement had been notified and already departed the scene. Reportedly, the locks on up to ten storage containers were cut and the contents stolen. Two additional gauges were stolen from another licensee, but were recovered on site. The gauges were not co-located and reportedly the stolen gauge was locked within a jobsite box, within a locked storage container. The Agency is actively inquiring if the gauge handle was properly locked and if the gauge was stolen within its transport container.

"Agency inspectors will perform a reactionary inspection this week, obtain a copy of the police report to update Nuclear Material Events Database, and any other updates added as they become available."

AGREEMENT STATE REPORT - STUCK FIXED GAUGE SHUTTER

The following information was provided by the Mississippi State Department of Health (MSDH) via email:

"The licensee, Tronox, LLC in Hamilton, Mississippi (Monroe County) reported a fixed gauge (Ohmart SHF-2-30 Serial Number 5319GK, 200 mCi Cs-137) [with a] stuck shutter to Mississippi State Department of Health on late Friday afternoon (9/23/22). It was discovered [on] 9/22/22 at 1557 CDT.

"The failure was identified during calibration activities being performed by a BBP representative who is an authorized Ohmart representative.

"The source shutter failure appears to be caused by age and corrosion. No exposure has been received by Tronox personnel and the unit did not leave its normal operating position. A certified Ohmart representative will replace the shutter in place.

"MSDH has asked for a timeline on the replacement, a current survey reading at the restricted area boundary, and what additional precautions have been taken to assure no unnecessary exposures."

The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:

The licensee will notify NRC Region IV inspection staff.

SAFETY SYSTEM INOPERABILITY

The following information was provided by the licensee via email:

"At 1608 [EDT] on September 30, 2022, it was discovered that both trains of the chemical volume and control system were simultaneously inoperable due to an unisolable piping flaw inside containment detected during plant pressurization in preparation for startup following a refueling outage.

"St. Lucie Unit 2 was not affected and remains at 100 percent power.

"This event is being reported pursuant to 10CFR50.72(b)(3)(v)(D).
